Thank you both for your replies.
I think writing it was a good experience. I hadn't vocalized that experience before yesterday in Therapy. My T told me the previous session that he thought it would be good to tell that story, so I spent the better part of the previous week picking apart those events. Vocalizing and then writing that out was a release. I feel less burdened. I don't feel any panic when I think about those events right now. Events which a few months previous would visit me as flashbacks.
I also feel I actually quite heavily identify with the poem (I don't want to say "like"). I wasn't sure last night and spent a few hours re-reading what I just wrote.
“what matters most is how well you walk through the fire”
